The former policeman was found last July in Budapest after an extensive search by the Sun newspaper, in conjunction with the Simon Wiesenthal Centre.
Csizsik-Csatáry, who topped the Centre’s list of wanted Nazi criminals before his arrest, lived in Canada for decades following the Second World War, where he acted as an art dealer. He left the country in 1997, when his citizenship was revoked on the basis that he had lied about his previous nationality, which he claimed was Yugoslavian.
He denies the allegations, stating that he simply intermediated between German and Hungarian officials.
Ms Bagoly told the Associated Press that, given the special importance of the trial, proceedings are expected to begin within three months.
